(I say "feet" for clarity; one could use any consistent length measure.) Or, if you will accept my picture below, * d | a | o | y R Theta | *___)______________| x then Grade = y/x (Multiply by 100 to express as a percentage.) and Theta = arctan(y/x) So a grade of 100% is a 45 degree angle. A cliff has an infinite grade. --------------------------------------------------------------------------- Ball Bearing Grades (Bill Codding peda@simplicity.Stanford.EDU) (Harry Phinney harry@hpcvlx.cv.hp.com) Following is a description of the different grades of ball bearings. The grade specifies the sphericity of the balls in millionths of an inch. Thus, grade 25 are round to 25/10^6, while grade 1000 are good to 1/1000 (i.e. not all that round, but probably good enough for our uses). Grade 25: the highest quality normally available, aka "Campagnolo quality": hardened all the way through, best alloys, coatings, roundness, and durability. Evidently, a recent bottom-bracket overhaul article in "Bicycling Plus Mountain Bike" magazine recommended these. Campy's tech reps claim that the bearings in a set (usually in a little paper bag) are matched. One should not mix bearings from different sets. Grade 200: mid-range Grade 1000: seems to be the lowest, may only be surface hardened. Good sources for ball bearings: Your local bike shop (make sure you're getting the grade you want) Bike Parts Pacific Bike Nashbar 1-800-NASHBAR ($1-$3 per 100 Grade 25) The Third Hand 1-916-926-2600 ($4-$7 per 100 Grade 25) --------------------------------------------------------------------------- Tour de France Jerseys (Chris Murphy murphyc@bionette.CGRB.ORST.EDU) Chauner and Halstead (1990) in "The Tour de France Complete Book of Cycling" explain: YELLOW Jersey -- Overall leader, first awarded during the 1919 race (TdF started in 1903); yellow to match the paper used to print L'Auto (Automobile Cyclisme), a French newspaper about bike racing. POLKADOT Jersey (White w/red dots) -- Best climber, determined by points scored by the first 3 to 15 riders finishing selected mountain stages (number of riders awarded points varies with the difficulty of the stage). First awarded 1933. GREEN Jersey -- Points jersey, usually won by sprinter-types, with points given to the first 25 riders to finish each stage. First awarded 1953. YELLOW Hats -- First place team, determined by combined elapsed times of the the team's top 3 riders. In the event of a rider leading the race and also deserving one of the other jerseys, the race leader wears yellow, and the 2nd place in the category wears the category jersey. --------------------------------------------------------------------------- Major Tour Winners 1947-1990 (Tim Smith tsmith@gryphon.CTS.COM) [Ed note: I'm hoping Tim won't be too upset if I add to the list he posted.

The Giro started in 1909, and was not held 1915-1918 and 1941-1945. Source: 1947-1982: "La Fabuleuse Histoire du Cyclisme" by Pierre Chany. 1982-1988: my fallible memory. Would someone complete 1983 and 1984, and correct any mistakes? Thanks. One interesting observation: almost all the winners of the Tour were big names in their time (yes, even Charly Gaul and Jean Robic.) There were no same-year winners of the Tour and the Giro before 1949. In fact, the first year a non-Italian won the Giro was 1950. --------------------------------------------------------------------------- Bike Trailers [Ed note: The posting I saved on bike trailers is over 145k bytes, so if you want a copy see the section on "Archives".] --------------------------------------------------------------------------- One Less Car T-Shirts (Alayne McGregor alayne@gandalf.UUCP) (Ed Ravin panix!eravin@cmcl2.nyu.edu) The T-shirts are produced by Transportation Alternatives, a New York City bicycle activist group. They're 100% cotton, have the TA logo on the front, and ONE LESS CAR on the back. Call TA for colors and sizes currently in stock. They're US$15 each. No refunds or exchanges. Allow 6 weeks for delivery. For people who have to drive but feel guilty about it, they also have "I'm Polluting the Atmosphere" bumper stickers at 3 for $5. Send orders to: Transportation Alternatives 92 Saint Marks Place New York, NY 10009 USA attn: One Less Car I happen to have one of these shirts in my closet right now. Causes lots of comments when my covivant and I ride our tandem with both us wearing our shirts. --------------------------------------------------------------------------- Panniers and Racks (Sharon Pedersen pedersen@cartan.berkeley.edu) This is a condensed version of a longer article on panniers, low-rider racks, loading and generators. --Sharon pedersen@cartan.berkeley.edu --PANNIERS-- Price--cheaper may not be better, if they fall apart. Commuting to school entails stuffing sharp-cornered books into them thus making sturdiness as important here as for touring. Cut--an angled cut may make those books not fit so well. Pockets--convenient for organization, but cuts down on versatile use of space. You can use stuff sacks for organization instead of pockets. One big and one small pocket on each pannier is plenty. Fastening--lots of options: bungees and hooks, or fixed placement hooks, or straps with buckles or cams. Bungees and hooks have been just fine in my own road experience, but for off-road riding, you will want more security. However, don't get a system with so many attachments that you can't stand to take the panniers on/off. Brands--the following is a by no means exhaustive list, with telegraphic comments made in 1988. Check local stores since features may have changed since then. Eclipse--(no comment); Kirtland--tourers like them; MPacks--panniers made by an actual bike tourer, Mike Center, in Santa Rosa, CA, (707) 545-4624; Maddens--made in Boulder, "superior construction at better than average cost" yeah! (I love mine, write for more glowing testimonials); Performance--low-cost, non-spring attachment; Rhode Gear--expensive; Tailwind--aerodynamic, rigid attachment. --LOW-RIDER RACKS-- Some manufacturers: Bruce Gordon, Blackburn, Vetta, Voyager. The Bruce Gordons are more expensive (~$70 in 1988) but are designed with clearance for the quick-release skewer so you don't have to pry them apart to take the front wheel off. --REAR RACKS-- (No comment in the original article; Blackburns seem to be the standard and durable enough.) --LOADING-- Balance the load side-to-side and, if possible, fore-and-aft. Keep heavier items low and towards the bottom bracket. Rider, bike and luggage together should have 55-60% of weight on rear wheel; remainder on front. Bike with front low-riders is quite stable. --GENERATORS-- The usual location on the left seat-stay interferes with panniers. Mount the generator on the right seat-stay facing the other way, and it will work fine, despite rotating "backwards." Or go with a generator under the bottom bracket, which will have the advantage of putting the wear on the tread rather than the sidewall of the tire. --------------------------------------------------------------------------- Helmets The wearing of helmets is another highly emotional issue that has been debated many times on rec.bicycles. On one side, you have the cyclists who feel that they can do without - the helmet is too hot, uncomfortable, or they feel they just don't need it. On the other side, you have the cyclists who wouldn't be caught riding without a helmet - they like their head (and brains) they way they are. Statistics show that three-fourths of the more than 1000 bicycling deaths each year are caused by head injuries. Of those killed, half are school age children. According to one study, a helmet can reduce the risk of head injury by 85%. Consumer Reports did a review of bicycle helmets in the May 1990 issue. While their report is not what one would see in a cycling magazine, it does contain some useful and valuable information. Their tests showed that no-shell helmets work just as well as hard-shell helmets, and in fact, the top 9 helmets in their ratings are no-shell models. There is some controversy about whether no-shell helmets "grab" the pavement instead of sliding on impact. If the helmet grabbed, it might lead to more serious neck or spinal injury. This topic has been hotly debated in rec.bicycles, and some studies are in progress to see if this is true. There are two standards systems for helmets - ANSI (American National Standards Institute) and Snell (the Snell Memorial Foundation). The Snell tests are more demanding than ANSI, and a Snell-certified helmet will have a green Snell sticker inside. Some helmets claim they pass Snell, but unless there's a sticker in the helmet, you can't be sure. Snell also tests samples of certified helmets to make sure they still meet the standards. --------------------------------------------------------------------------- Clothing materials (Jim Carson carson@mu.rice.edu) [Ed note: From a summary Jim posted] Polarlite Fluffy, fleecy stuff also called Polarplus and Synchilla. Comfortable. Incredibly warm, especially under something that breaks the wind. Doesn't wick moisture out very well. Breathes very well. Supplex (nylon) Comfortable. It is breathable and water repellent (but NOT water proof). Seems to absorb a small amount of water if it is really getting drenched Merino (wool) From a "breed of fine-wooled white sheep originating in Spain and producing a heavy fleece of exceptional quality." I guess you could treat this as normal 100% wool. Thermax An improvement on Polypro. The big advantage is heat resistance so you can put it in the dryer. Balance that against the extra cost. CoolMax This stuff seems more like a plastic bag than the revolutionary wicking material it is advertised as. Dacron Trademark name for Dupont polyester. Woven fabric made from dacron is similar to nylon ripstop or taffeta, but not as stretchy. Many of the better clothing insulations are made from dacron. They are usually refered to by more specific trademark names, like quallofil, hollofil, polarguard, and dacron-88. Lycra Used for its stretch, mostly a warm weather (>65 degrees) thing. GoreTex A teflon based membrane with microscopic holes. Gortex's claim to fame is that it will let water vapor (from perspiration) through, but not liquid water (rain). It blocks wind fairly well too. The membrane is delicate, so it always comes laminated between 2 layers of other material. It does not breathe enough. There are less expensive alternatives. Polypropylene Does not wick very well. Can be uncomfortable. Troublesome to care for (e.g. can pill badly) Will keep you fairly warm if soaked. Not very wind resistant. Melts in the dryer. Capilene Wicks moisture away. Very comfortable. Comes in different weights for more/less warmth. [lots of favorable things about it... only really unfavorable thing is the co$t] 60/40 cloth - This is a cloth with nylon threads running one direction, cotton in the other. It was the standard wind parka material before Goretex came along, and is considerably less expensive. Good wind resistance, fairly breathable. Somewhat water resistant, especially if you spray it with Scotchguard, but won't hold up to a heavy rain. --------------------------------------------------------------------------- Seats Seats are a very personal thing, for obvious reasons. There are several types of seats: Leather Seats like the Brooks models. Usually used by hard-core riders. Requires breaking in before it's really comfortable. Padded The usual bike seat, sometimes refered to as "anatomic". Has padding where your "sit bones" (bottom of pelvis) supposed to rest. Gel Like the padded seats, except they have a gel (e.g. Spenco Gel) in them for additional padding. Reportedly, the gel can harden and/or shift, making the seat uncomfortable. There are several types of seat pads (gel filled, containing an air bladder, etc) that can be fitted over the seat to make it more comfortable. If you are experiencing pain in delicate areas (especially you women readers) you should make sure your seat is adjusted correctly (see the section on seat adjustment). Women may need a women's type seat, which is wider in the back (women's sit bones are farther apart than men's). Most pain can be eliminated by a correctly adjusted seat, using a women's seat, and riding so your body becomes used to it. --------------------------------------------------------------------------- SIS Cable Info (Jobst Brandt jobst_brandt%40@hp1900.desk.hp.com) After Joe Gorin described the SIS "non-compressive" cable housing to me I got myself a sample to understand what the difference is. I believe "non-compressive" is a misnomer. This cable housing is NOT non-compressive but rather a constant length housing. As far as I can determine, and from reports from bike shops, this housing should not be used for brakes because it is relatively weak in compression, the principal stress for brake housing. SIS housing is made of 18 strands of 0.5mm diameter round spring steel wire wrapped in a 100mm period helix around a 2.5mm plastic tube. The assembly is held together by a 5mm OD plastic housing to make a relatively stiff cable housing. Because the structural wires lie in a helix, the housing length remains constant when bent in a curve. Each strand of the housing lies both on the inside and outside of the curve so on the average the wire path length remains constant, as does the housing centerline where the control cable resides. Hence, no length change. A brake cable housing, in contrast, changes length with curvature because only the inside of the curve remains at constant length while the outside (and centerline) expands. Shimano recommends this cable only for shift control but makes no special effort to warn against the danger of its use for brakes. It should not be used for anything other than shift cables because SIS housing cannot safely withstand compression. Its wires stand on end and have no compressive strength without the stiff plastic housing that holds them together. They aren't even curved wires, so they splay out when the outer shield is removed. Under continuous high load of braking, the plastic outer housing can burst leaving no support. Besides, in its current design it is only half as flexible as brake cable because its outer shell is made of structurally stiff plastic unlike the brake cable housing that uses a soft vinyl coating. Because brake cables transmit force rather than position, SIS cable, even if safe, would have no benefit. In contrast, with handlebar controls to give precise shift positioning, SIS housing can offer some advantage since the cable must move though steering angles. SIS housing has no benefit for downtube attached shifters because the cable bends do not change. --------------------------------------------------------------------------- Terminology (David Keppel pardo@cs.washington.edu) (Charles Tryon bilbo@bisco.kodak.com) Ashtabula Crank A one-piece crank -- the crank arm starts on one side of the bike, bends to go through the bottom bracket, and bends again on the other side to go down to the other pedal. Typically heavy, cheap, and robust. See ``cottered crank'' and ``cotterless crank''. Ashtabula is the name of the original manufacturer, I think. Biopace Chainring Chainrings that are more oval rather than round. The idea was to redistribute the forces of pedaling to different points as your feet go around, due to the fact that there are "dead spots" in the stroke. The concensus is pretty much that they work ok for novices, but get in the way for more experienced riders. Cassette Freewheel A cassette freewheel is used with a freehub. The part of a normal freewheel that contains the pawls that transfer chain motion to the wheel (or allows the wheel to spin while the chain doesn't move) is part of the wheel hub. The cassette is the cogs, usually held together with small screws. Cleat A cleat attaches to the bottom of a cycling shoe. Older style cleats have a slot that fits over the back of the pedal, and in conjunction with toe clips and straps, hold your foot on the pedal. New "clipless" pedals have a specially designed cleat that locks into the pedal, sometimes with some ability to move side-to-side so as not to stress knees. Cottered Crank A three-piece crank with two arms and an axle. The arms each have a hole that fits over the end of the axle and a second hole that runs tangential to the first. The crank axle has a tangential notch at each end. A *cotter* is a tapered and rounded bar of metal that is inserted in the tangential hole in the crank arm and presses against the tangential notch in the crank axle. The cotter is held in place by a nut screwed on at the thin end of the cotter. Ideally, the cotter is removed with a special tool. Often, however, it is removed by banging on it with a hammer. If you do the latter (gads!) be sure (a) to unscrew the nut until the end of the cotter is nearly flush, but leave it on so that it will straighten the threads when you unscrew it farther and (b) brace the other side of the crank with something very solid (the weight of the bike should be resting on that `something') so that the force of the banging is not transmitted through the bottom bracket bearings. Cotterless Crank A three-piece crank with two arms and an axle. Currently (1991) the most common kind of crank. The crank axle has tapered square ends, the crank arms have mating tapered square ends. The crank arm is pressed on and the taper ensures a snug fit. The crank arm is drawn on and held in place with either nuts (low cost, ``nutted'' cotterless cranks) or with bolts. A special tool is required to remove a cotterless crank. Crank Axle The axle about which the crank arms and pedals revolve. May be integrated with the cranks (Ashtabula) or a separate piece (cottered and cotterless). Fender Also called a ``mudguard''. Looked down upon by tweak cyclists, but used widely in the Pacific Northwest and many non-US parts of the world. Helps keep the rider cleaner and drier. Compare to ``rooster tail''. Frame Table A big strong table that Will Not Flex and which has anchors at critical places -- dropouts, bottom bracket, seat, head. It also has places to attach accurate measuring instruments like dial gauges, scratch needles, etc. The frame is clamped to the table and out-of-line parts are yielded into alignment. High-Wheeler A bicycle with one large wheel and one small wheel. The commonest are large front/small rear. A small number are small front/large rear. See ``ordinary'' or ``penny-farthing'' and contrast to ``safety''. Hyperglide Freewheel Freewheel cogs with small "ramps" cut into the sides of the cogs which tend to pull the chain more quickly to the next larger cog when shifting. Ordinary See ``penny-farthing''. Penny-Farthing An old-fashioned ``high wheeler'' bicycle with a large (60", 150cm) front wheel and a much smaller rear wheel, the rider sits astride the front wheel and the pedals are connected directly to the front wheel like on many children's tricycles. Also called ``ordinary'', and distinguished from either a small front/large rear high wheeler or a ``safety'' bicycle. Rooster Tail A spray of water flung off the back wheel as the bicycle rolls through water. Particularly pronounced on bikes without fenders. See also ``fender''. Safety Named after the ``Rover Safety'' bicycle, the contemporary layout of equal-sized wheels with rear chain drive. Compare to ``ordinary''. Spindle See ``crank axle''. Three-Piece Crank A cottered or cotterless crank; compare to Ashtabula. --------------------------------------------------------------------------- Maps (Jim Carson carson@rice.edu) BikeCentennial maps are not free, but you can get them without joining. To order stuff with Mastercard or Visa, you can call 1-800-933-1116 (24 hr). Maps are currently (May 1991) $6.95 each to "non-members," $4.95 each to "members." There are also small discounts for sets of maps and members in the continental US don't have to pay for surface shipping and handling. Scale of the maps is generally 1" = 4mi/6.4km. Certain areas are more detailed when necessary. I like the maps because they have lots of interesting features labeled (campgrounds, grocery stores, major changes in elevation, historical info about the region,...), they're printed on a water-resistant paper, and they fit nicely into a handlebar bag map case. As of May '91, there are two and a half transcontinental (W-E) routes an east coast (N-S) route, a west coast route (N-S), and numerous routes among the various parks in the western U.S. and Canada. [I say "2 1/2 transcontinental routes" because the southern portion of the transcontinental route from TX to FL is not in print though the maps are "done."] Membership is $22/annually, and they have a lifetime membership available.

It is amazing how many times I have found myself standing around after a ride talking with other women about saddles. This article came from those discussions and an informal survey of woman's saddle preferences. This is a dynamic article and changes on occassion, so if you have comments please contact me (pamela@keps.kodak.com) and I will incorporate your comments. Just as women are different from men, we are also different from each other. Since (fortunately) there is no mold into which we were all poured, what works for one woman may not work for another. While this is an article on women's saddles, since so many other things can contribute to potential saddle pain, it will also address some of these issues as well. First, insure that your bike fits properly. Many women end up with overly padded shorts and a big fat thickly padded saddle instead of with a bike that fits. No saddle will be comfortable if the bike is too big, or set up incorrectly. It is important to find someone who knows about fit and specifically about women's fit and get the bike set up properly before making other changes. It isn't always easy to find someone willing to take the time, but when you find a shop that will, give them lots of business and send your friends there! In addition to being more comfortable, a bike that really fits will also handle better than one that is improperly sized. Most production bikes are built proportionally for the average man. Using the old guidelines of sizing a bike by straddling the top tube may leave you a bike with a top tube that is too long. It is not necessary to run out and buy a new bike right away if the top tube on your current bike is too long. Using a shorter stem on a this bike may give you a more comfortable reach. Very short stems, less than 40 mm, are available, but may have to be special ordered. Some shops use a fitting system called the Fit Kit. The numbers generated from the Fit Kit are just guidelines and may not work for everybody, especially women. It is important to RIDE your bike and possibly make more adjustments to achieve a perfect fit. Others may use an infinitely adjustable stationary bike. One has been developed by Ben Serotta to help choose the perfect size bike - whether it is a Serotta or not. Adjustable stems are available to help you and the shop pick a perfect length stem the first time. Unless your current bike is a really, really poor fit, you should be able to make a few relatively inexpensive changes to improve the fit. Then when upgrading or buying a new bike, use what you have learned to buy a bike that fits better. One option is to simply select a bike with a shorter seat tube, combined with a longer seatpost, to get a shorter top tube length. This will work for taller women, but there is a limit of how short you can make a top tube with two 700C wheels. Several manufacturers have started building bikes proportionally sized for women to specifically address our needs. For small women, these bikes may have a smaller front wheel to get the shorter top tube, but not all women's bikes have a 24" front wheel. Some have two 26" or 700C wheels, depending on size and geometry. In addition to a shorter top tube, women's bikes may also have smaller brake levers, narrower handlebars, shorter cranks and wider saddles. Georgena Terry was the pioneer in this area, but many other manufacturers now build women's bikes. They may cost a little more than a comparably equipped man's bike, due to higher production costs for fewer number of parts. But, I believe that the extra initial cost to get a properly fit bike will pay off in the long run, since you will either stop riding an uncomfortable or poorly fitting bike, or you will eventually replace the poorly fitting parts at additional cost. Of course, as I said earlier, we are all different and many women may not need any special adjustments made to their non-custom off-the-shelf bikes. Now to saddles. A woman's hip bones tend to be set farther apart than a man's. (This is a design feature to help with childbirth!) Every woman is different, and there are some women out there with narrower hip bones. To determine where you sit bones are, sit on a low curb. Sorry, a chair won't do! When you sit on the curb, you will ba able to feel your sit bones. This is what you want supported by your bike saddle. Avocet used to (and maybe still does) run a great ad showing a hip bone sitting on a saddle. With a saddle that's too narrow, a woman may find herself straddling it, or slipping off of one side and pinching nerves - which may eventually cause the legs or feet to go numb. Of course, a saddle that's too wide may also cause problems. A saddle that's slightly wider in the back (than the man's saddle that comes on most stock bikes) may offer better support for the sit bones. I have quite a few retired women's saddles with depressed gel indicating exactly where I my bones are, which for me is close to the edge. Actually, looking at your old saddle will tell you a lot about where you do and do not need support! It's important to try out several different saddles to find one that fits. Remember, we are all different. Unfortunately no one manufacturer makes different sized women's saddles - but the widths do vary from manufacturer to manufacturer - so for example, if the Terry is too wide or too narrow, try the Vetta or Avocet or some other brand. Ask your local dealer to let you put your bike on a trainer in the shop and try sitting on and riding a few of his saddles. Saddles are fairly easy to change and a good shop should be willing to let you try this. There are several women's saddles on the market, many of which are made with some form of gel. I have used (and retired) several of these with no complaints. The gel does compress after a while (regardless of sex), so these saddles do have to be replaced (for me it's every 10,000 miles). Many women who responded to my survey said that they have the nose of their saddle tilted slightly forward to alleviate pressure on the soft tissue. A large variety of saddles were used with this method including the Brooks leather. One rider pointed out that having a seatpost with infinitely adjustable angles, like the American Classic, will help one to find the perfect angle. With the rachet type adjustment of most, she was never able to get the angle quite right. One problem with having the saddle tilted too far forward is that you may end up with two much weight/pressure on your wrists and hands. The result is numb hands and pain in the lower back. In John Forester's "Effective Cycling" book, he suggests getting a cheap plastic saddle and carving out a depression in the area where the labia would normally rest. This would place the weight on the sit bones where it belongs, and remove it from the genital area, where it does not. Two new saddles were introduced recently which specifically address this issue, the Terry Women's and the Miyata Pavea. Both are shorter and wider than the typical man's saddle and both have a hole in the nose to suspend soft tissue. These saddles should be comfortable when level. The Miyata leaves the hole exposed, while the Terry is covered in an open-cell low-density foam. I have used both the Terry and the Miyata. I've received lots of positive comments from women (and men) about their experiences with these saddles. The men seem to notice the difference more after the ride later in the evening :) :) :) I recently completed a 750 mile ride on the back of a tandem in 85.5 hours. That's a lot of time on a saddle. I'd been using the Terry for over 6 months and it worked great on everything up to 200 miles. But 400 miles into the trip, I was ready to rip the foam out of the hole. Once the swelling started, the presence of the foam became unbearable. Even though there was no plastic shell underneath, there was still something! I asked our crew person to see if he could find the Miyata saddle. It's often quite difficult to find women's products, and I was almost shocked when he showed up 20 minutes later with this wonderful saddle with an exposed hole. He had found the Miyata. The difference was immediately noticeable. I probably would have finished the ride without it, but I wouldn't have been in a good mood for days! The Miyata is a little harder under the sit bones than the Terry, but that's not where I was experiencing pain. Of course the saddle is different looking and draws lots of comments and sexual innuendos, but it saved my ride. My male tandem partner is now looking into making a similar type modification to his saddle before our next really long event. Not all women like the wider saddles. Some women find all women's saddles too wide. Several women responded to the survey saying they prefer a man's saddle. Some of these even felt they had wide hip bones. For those who use a narrow saddle, finding one that was flat on top seemed to help with the above mentioned problems. Others who liked various women's saddles still found them a little thick in the middle, even if they were the right width in the back. Terry has announced a racing version of their saddle, which has a narrower nose. This saddle was supposed to be available in June, 1992, but a manufacturing problem has delayed its delivery to customers. I will update this article as soon as I get to test ride one. Someday, maybe we will see women's saddles in various widths. We must create the demand though. Other suggestions for improved saddle comfort including trying different shorts. Shorts that bunch up in front may cause discomfort. Shorts fit differently in and out of the saddle, so look down while you are on the bike. Sprinkling powder in the shorts may help keep you dry and saddle sore free on a warm day. A little vasoline may also help with prevention or treatment of saddles sores. I can't stress enough that each woman is different and no one saddle is perfect for all of us. Just because a local or national racer, or your friend, or *Pamela* uses a particular type of saddle doesn't mean that it will work for you. Don't let anyone intimidate you into riding something that is uncomfortable, or changing the angle of your saddle because it's different. Use the setup that's most comfortable for you. Among the saddles recommended by respondents were Terry Women's Miyata Pavea WaveFlo Avocet Women's Racing saddle Viscount saddle San Marco Regal women's Selle Italia Turbo Brook's B-17 Brook's Pro (Of course some women hated saddles that others raved about! Did I mention that we are all DIFFERENT) Specialty women's products are available through The Womyn's Wheel, 540 Lafayette Rd, Suite 7, Hampton, NH, 03842-3344, phone 603-926-4939, or hopefully at your local bike shop - just keep asking them!! --------------------------------------------------------------------------- Women's Bikes (Lynn Karamanos karamano@esd.dl.nec.com) Here's a summary of the info I received on whether or not to purchase a Terry bike. 1.) First, find a good bike shop, one that will try to find a bike that fits you, not just sell you what they have in stock. 2.) Ride many different bikes to see what's best for you. You may be able to find other bikes that fit just as well as a Terry once you've made some adjustments/replacements (stem, crank arms, etc.). 3.) If you can't find any other bike to fit you, then a Terry's worth the extra money. 4.) Except for about two people who sent me email, everyone who's ridden a Terry has loved it. Even those two people said they knew others who loved Terry bikes. Bottom line: the fit depends on your build. Women with long legs/short torso seem to be the ones who like them, not necessarily just short women. 5.) Also a few people mentioned that there are other road bikes that are specifically "designed for women" or that fit women well. The names mentioned: Fuji, Miyata, Bridgestone, Specialized (Sirrus). Also, someone mentioned that the same production line in Japan that makes Terry "proportioned" bikes also makes them under other labels. (Also one mountain bike was named, Mongoose Hilltopper, and two hybred bikes, Univega Via Activa and Giant Inova.) 6.) Something to keep in mind if you buy a Terry with a small front wheel... replacement tubes and tires for smaller wheels could be more difficult to find and/or more expensive. 7.) In case you're looking at older model Terry's, a few people mentioned that until a couple years ago, some Terry bikes were $200-$300 less than they are now. ---
